Looks to me that it may just be loading up, like idling too long
before you shut down. Take the thing out, get it up to temp and make a
run with it, then shut it down and look at the plugs. If they are
still wet after making an at speed run, you may have a too rich fuel/
oil ratio, or a carb problem.
